. REENFORCING CHAIR.

To all whom it may concern:

Be it known that I, WILLIAM E. WHITE, a citizen of theUnited States, and resident of Chicago, in thelcounty of Cook and State of Illinois, have invented certain new and useful Improvements in a Reenforcing Chair, of which the following is aspecification.

My invention relates to reenforcing devices and particularly to a novel chair or support for reenforcing rods.

One of the objects of-my invention is to provide a device of extreme simplicity, which may be cheaply produced and possess many if not all of the advantages of the more expensive and complicated devices.

, The desired result is secured by utilizing .verse'parts' of a U-shaped member.

wire as the exclusive-material for constructing the device and forming the wire sectlons into two rectangularly disposed inverted U- shaped elements, the four legs being spaced ninety degrees apart. The transverse members of the U-shaped elements are welded at theifintersection, and in one form of the device I providebraces between the respective legs. In order to form a seat for a reenforcing rod I provide a third U-shaped member which is welded'to one of the trans- This seat forming device may be composed of soft wire adapting it to be twisted over the top of a bar or it may be of stiffwire and constitute merely a seat without-being twisted. The invention will be more readily understood. by reference to the accompanying drawing, wherein, I I

Fig. 6 is a View taken at right'angles to that of Fig; 5; and

Fig. 7 is a sectional view on the line 77 of Fig. 5. i

In the drawings it will be seen that the device comprises generally a pair of U shaped members, each having legs 10 and a transverse element 11. One of the U-shaped Application filed August 12, 1921. Serial Flo. 491,834.

members is slightly shorter than the other,

and the transverse member thereof underlies and is Welded to the corresponding part of the longer member at their intersection as indicated at 12. A third U-shaped member betweenthem a seat for enforcing rods 16, 17. Of course, a seat member of soft wire may be used for holding a single rod, or a stilf wire holding member may be used for retaining the crossedrods, this being Wholly a matter of choice.

It will be noted that in the construction described the legs 10 are flared somewhat, and are adapted to form a stable structure not likely to be displaced and comprising unusual strength for the weight of material utilized.

In the construction of Figs. 5, 6, and 7, the same U-shaped elements are employed, the legs 18 being considerably longer and preferably somewhat sharpened at their ends. Theyare'welded at their intersection and, at a point intermediate their ends, are provided with, brace rods 19 which are welded to the legs and to each other. These rods serve the double purpose of bracing the legs and of constituting limit stops for the downward movement of the chair in earth. The chair is intended for use insupporting reenforcing rods 20 for concrete roadways. A U-shaped seat member 21, of soft or stiff wire, will be employed for holding the rods. Obviously the construction is capable of much modification and I do. not wish to be limited except as indicated in the appended claims. It will be apparent that if desired I may provide brace rods at the lower ends of the chair shown in Figs. 1 to4 and, by lengthening the legs of this chair, such a construction so braced may be employed for road work instead of the form shown in Figs. 5 to 7 in which the ends of the chair enter the earth.

I claim: 1. In a reenforcing chair, the combination of a pair of staples rectangularly disposed and welded at the point of engagement between. the transverse members or" the staples, and means secured to the chair for forming a, seat for e reenforcing rod.

2. In a device of the eless described, the combination of a pair of U-sheped members the transverse elements of which are Welded at their intersection, and a third U-sheped element welded to one of said transverse members, the opening in the lest-named U- Len er) 3. in e reenforcing oheir, the combination of engularly disposed U-shaped members joined at their intersections and providing four legs, and transverse braces extending between the legs at a, point between the ends thereof said braces being positioned to serve as limit stops for the downward movement of the chairs in earth.
